Where substituent groups are specified by their conventional chemicalformulae, written from left to right, they equally encompass thechemically identical substituents, which would result from writing thestructure from right to left, e.g., —CH₂O— is intended to also recite—OCH₂—.

The term “poly” as used herein means at least 2. For example, apolyvalent metal ion is a metal ion having a valency of at least 2.

“Moiety” refers to a radical of a molecule that is attached to theremainder of the molecule.

The symbol

The term “alkyl,” by itself or as part of another substituent, means,unless otherwise stated, a straight or branched chain, or cyclichydrocarbon radical, or combination thereof, which may be fullysaturated, mono- or polyunsaturated and can include di- and multivalentradicals, having the number of carbon atoms designated (i.e. C₁-C₁₀means one to ten carbons). In some embodiments, the term “alkyl” means astraight or branched chain, or combinations thereof, which may be fullysaturated, mono- or polyunsaturated and can include di- and multivalentradicals. Examples of saturated hydrocarbon radicals include, but arenot limited to, groups such as methyl, ethyl, n-propyl, isopropyl,n-butyl, t-butyl, isobutyl, sec-butyl, cyclohexyl, (cyclohexyl)methyl,cyclopropylmethyl, homologs and isomers of, for example, n-pentyl,n-hexyl, n-heptyl, n-octyl, and the like.

The term “arylene” by itself or as part of another substituent means adivalent radical derived from an aryl.

The term “heteroarylene” by itself or as part of another substituentmeans a divalent radical derived from heteroaryl.

The terms “alkoxy,” “alkylamino” and “alkylthio” (or thioalkoxy) areused in their conventional sense, and refer to those alkyl groupsattached to the remainder of the molecule via an oxygen atom, an aminogroup, or a sulfur atom, respectively.

The term “heteroalkyl,” by itself or in combination with another term,means, unless otherwise stated, a stable straight or branched chain, orcyclic hydrocarbon radical, or combinations thereof, consisting of thestated number of carbon atoms and at least one heteroatom. In someembodiments, the term “heteroalkyl,” by itself or in combination withanother term, means a stable straight or branched chain, or combinationsthereof, consisting of the stated number of carbon atoms and at leastone heteroatom. In an exemplary embodiment, the heteroatoms can beselected from the group consisting of B, O, N and S, and wherein thenitrogen and sulfur atoms may optionally be oxidized and the nitrogenheteroatom may optionally be quaternized. The heteroatom(s) B, O, N andS may be placed at any interior position of the heteroalkyl group or atthe position at which the alkyl group is attached to the remainder ofthe molecule. Examples include, but are not limited to, —CH₂—CH₂—O—CH₃,—CH₂—CH₂—NH—CH₃, —CH₂—CH₂—N(CH₃)—CH₃, —CH₂—S—CH₂—CH₃, —CH₂—CH₂,—S(O)—CH₃, —CH₂—CH₂—S(O)₂—CH₃, —CH═CH—O—CH₃, —CH₂—CH═N—OCH₃, and—CH═CH—N(CH₃)—CH₃.

For heteroalkylenegroups, heteroatoms can also occupy either or both of the chain termini(e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino, andthe like). Still further, for alkylene and heteroalkylene linkinggroups, no orientation of the linking group is implied by the directionin which the formula of the linking group is written. For example, theformula —C(O)₂R′— represents both —C(O)₂R′— and —R′C(O)₂—.

The terms “cycloalkyl” and “heterocycloalkyl”, by themselves or incombination with other terms, represent, unless otherwise stated, cyclicversions of “alkyl” and “heteroalkyl”, respectively. Additionally, forheterocycloalkyl, a heteroatom can occupy the position at which theheterocycle is attached to the remainder of the molecule. Examples ofcycloalkyl include, but are not limited to, cyclopentyl, cyclohexyl,1-cyclohexenyl, 3-cyclohexenyl, cycloheptyl, and the like. Examples ofheterocycloalkyl include, but are not limited to,1-(1,2,5,6-tetrahydropyridyl), 1-piperidinyl, 2-piperidinyl,3-piperidinyl, 4-morpholinyl, 3-morpholinyl, tetrahydrofuran-2-yl,tetrahydrofuran-3-yl, tetrahydrothien-2-yl, tetrahydrothien-3-yl,1-piperazinyl, 2-piperazinyl, and the like.

The terms “halo” or “halogen,” by themselves or as part of anothersubstituent, mean, unless otherwise stated, a fluorine, chlorine,bromine, or iodine atom. Additionally, terms such as “haloalkyl,” aremeant to include monohaloalkyl and polyhaloalkyl. For example, the term“halo(C₁-C₄)alkyl” is mean to include, but not be limited to,trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, andthe like.

The term “aryl” means, unless otherwise stated, a polyunsaturated,aromatic, substituent that can be a single ring or multiple rings(preferably from 1 or 2 or 3 rings), which are fused together or linkedcovalently. The term “heteroaryl” refers to aryl groups (or rings) thatcontain from one to four heteroatoms. In an exemplary embodiment, theheteroatom is selected from B, N, O, and S, wherein the nitrogen andsulfur atoms are optionally oxidized, and the nitrogen atom(s) areoptionally quaternized. A heteroaryl group can be attached to theremainder of the molecule through a heteroatom. Non-limiting examples ofaryl and heteroaryl groups include phenyl, 1-naphthyl, 2-naphthyl,4-biphenyl, 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 3-pyrazolyl,2-imidazolyl, 4-imidazolyl, pyrazinyl, 2-oxazolyl, 4-oxazolyl,2-phenyl-4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl,5-isoxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 2-furyl, 3-furyl,2-thienyl, 3-thienyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-pyrimidyl,4-pyrimidyl, 5-benzothiazolyl, purinyl, 2-benzimidazolyl, 5-indolyl,1-isoquinolyl, 5-isoquinolyl, 2-quinoxalinyl, 5-quinoxalinyl,3-quinolyl, and 6-quinolyl. Substituents for each of the above notedaryl and heteroaryl ring systems are selected from the group ofacceptable substituents described below.

For brevity, the term “aryl” when used in combination with other terms(e.g., aryloxy, arylthioxy, arylalkyl) includes both aryl and heteroarylrings as defined above. Thus, the term “arylalkyl” is meant to includethose radicals in which an aryl group is attached to an alkyl group(e.g., benzyl, phenethyl, pyridylmethyl and the like) including thosealkyl groups in which a carbon atom (e.g., a methylene group) has beenreplaced by, for example, an oxygen atom (e.g., phenoxymethyl,2-pyridyloxymethyl, 3-(1-naphthyloxy)propyl, and the like).

Each of the above terms (e.g., “alkyl,” “heteroalkyl,” “aryl” and“heteroaryl”) are meant to include both substituted and unsubstitutedforms of the indicated radical. Preferred substituents for each type ofradical are provided below.

Substituents for the alkyl and heteroalkyl radicals (including thosegroups often referred to as alkylene, alkenyl, heteroalkylene,heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, andheterocycloalkenyl) are generically referred to as “alkyl groupsubstituents,” and they can be one or more of a variety of groupsselected from, but not limited to: —R′, —OR′, ═O, ═NR′, ═N—OR′, —NR′R″,—SR′, -halogen, —SiR′R″R′″, —OC(O)R′, —C(O)R′, —CO₂R′, —CONR′R″,—OC(O)NR′R″, —NR″C(O)R′, —NR′—C(O)NR″R′″, —NR″ C(O)₂R′,—NR′″″—C(NR′R″R′″)═NR″″, —NR″″—C(NR′R″)═NR′″, —S(O)R′, —S(O)₂R′,—S(O)₂NR′R″, —NR″SO₂R′, —CN, —NO₂, —N₃, —CH(Ph)₂, fluoro(C₁-C₄)alkoxy,and fluoro(C₁-C₄)alkyl, in a number ranging from zero to (2m′+1), wherem′ is the total number of carbon atoms in such radical. R′, R″, R″″ andR′″″ each preferably independently refer to hydrogen, substituted orunsubstituted heteroalkyl, substituted or unsubstituted aryl, e.g., arylsubstituted with 1-3 halogens, substituted or unsubstituted alkyl,alkoxy or thioalkoxy groups, or arylalkyl groups. When a compound of theinvention includes more than one R group, for example, each of the Rgroups is independently selected as are each R′, R″, R′″, R″″ and R′″″groups when more than one of these groups is present. When R′ and R″ areattached to the same nitrogen atom, they can be combined with thenitrogen atom to form a 5-, 6-, or 7-membered ring. For example, —NR′R″is meant to include, but not be limited to, 1-pyrrolidinyl and4-morpholinyl. From the above discussion of substituents, one of skillin the art will understand that the term “alkyl” is meant to includegroups including carbon atoms bound to groups other than hydrogengroups, such as haloalkyl (e.g., —CF₃ and —CH₂CF₃) and acyl (e.g.,—C(O)CH₃, —C(O)CF₃, —C(O)CH₂OCH₃, and the like).

Similar to the substituents described for the alkyl radical,substituents for the aryl and heteroaryl groups are generically referredto as “aryl group substituents.” The substituents are selected from, forexample: —R′, —OR′, ═O, ═NR′, —NR′R″, —SR′, -halogen, —SiR′R″R′″,—OC(O)R′, —C(O)R′, —CO₂R′, —CONR′R″, —OC(O)NR′R″, —NR″C(O)R′,—NR′—C(O)NR″R′″, —NR″C(O)₂R′, —NR′″″—C(NR′R″R′″)═NR″″,—NR″″—C(NR′R″)═NR′″, —S(O)R′, —S(O)₂R′, —S(O)₂NR′R″, —NR″SO₂R′, —CN,—NO₂, —N₃, —CH(Ph)₂, fluoro(C₁-C₄)alkoxy, and fluoro(C₁-C₄)alkyl, in anumber ranging from zero to the total number of open valences on thearomatic ring system; and where R′, R″, R″, R″″ and R″ are preferablyindependently selected from hydrogen, substituted or unsubstitutedalkyl, substituted or unsubstituted heteroalkyl, substituted orunsubstituted aryl and substituted or unsubstituted heteroaryl. When acompound of the invention includes more than one R group, for example,each of the R groups is independently selected as are each R′, R″, R′″,R″″ and R′″″ groups when more than one of these groups is present.

Two of the substituents on adjacent atoms of the aryl or heteroaryl ringmay optionally be replaced with a substituent of the formula-T-C(O)—(CRR′)_(q)—U—, wherein T and U are independently —NR—, —O—,—CRR′— or a single bond, and q is an integer of from 0 to 3.Alternatively, two of the substituents on adjacent atoms of the aryl orheteroaryl ring may optionally be replaced with a substituent of theformula -A-(CH₂)_(r)—B—, wherein A and B are independently —CRR′—, —O—,—NR—, —S—, —S(O)—, —S(O)₂—, —S(O)₂NR′— or a single bond, and r is aninteger of from 1 to 4. One of the single bonds of the new ring soformed may optionally be replaced with a double bond. Alternatively, twoof the substituents on adjacent atoms of the aryl or heteroaryl ring mayoptionally be replaced with a substituent of the formula—(CRR′)_(s)—X—(CR″R′″)_(d)—, where s and d are independently integers offrom 0 to 3, and X is —O—, —NR′—, —S—, —S(O)—, —S(O)₂—, or —S(O)₂NR′—.The substituents R, R′, R″ and R′″ are preferably independently selectedfrom hydrogen or substituted or unsubstituted C₁ or C₂ or C₃ or C₄ or C₅or C₆ alkyl.

“Ring” as used herein, means a substituted or unsubstituted cycloalkyl,substituted or unsubstituted heterocycloalkyl, substituted orunsubstituted aryl, or substituted or unsubstituted heteroaryl. A ringincludes fused ring moieties. The number of atoms in a ring is typicallydefined by the number of members in the ring. For example, a “5- to7-membered ring” means there are 5 or 6 or 7 atoms in the encirclingarrangement. Unless otherwise specified, the ring optionally includes aheteroatom. Thus, the term “5 to 7-membered ring” or “5 or 6 or 7membered ring” includes, for example phenyl, pyridinyl and piperidinyl.The term “5 to 7-membered heterocycloalkyl ring” “5 or 6 or 7-memberedheterocycloalkyl ring”, on the other hand, would include pyridinyl andpiperidinyl, but not phenyl. The term “ring” further includes a ringsystem comprising more than one “ring”, wherein each “ring” isindependently defined as above.

As used herein, the term “heteroatom” includes atoms other than carbon(C) and hydrogen (H). Examples include oxygen (O), nitrogen (N) sulfur(S), silicon (Si), germanium (Ge), and aluminum (Al).

The term “leaving group” means a functional group or atom which can bedisplaced by another functional group or atom in a substitutionreaction, such as a nucleophilic substitution reaction. By way ofexample, representative leaving groups include triflate, chloro, bromoand iodo groups; sulfonic ester groups, such as mesylate, tosylate,brosylate, nosylate and the like; and acyloxy groups, such as acetoxy,trifluoroacetoxy and the like.

The symbol “R” is a general abbreviation that represents a substituentgroup that is selected from substituted or unsubstituted alkyl,substituted or unsubstituted heteroalkyl, substituted or unsubstitutedaryl, substituted or unsubstituted heteroaryl, substituted orunsubstituted cycloalkyl and substituted or unsubstitutedheterocycloalkyl groups.

By “effective” amount of a drug, formulation, or permeant is meant asufficient amount of an active agent to provide the desired local orsystemic effect. A “Topically effective,” “pharmaceutically effective,”or “therapeutically effective” amount refers to the amount of drugneeded to effect the desired therapeutic result.

The term “pharmaceutically acceptable salt” is meant to include a saltof a compound of the invention which is prepared with relativelynontoxic acids or bases, depending on the particular substituents foundon the compounds described herein. When compounds of the inventioncontain relatively acidic functionalities, base addition salts can beobtained by contacting the neutral form of such compounds with asufficient amount of the desired base, either neat or in a suitableinert solvent. Examples of pharmaceutically acceptable base additionsalts include sodium, potassium, calcium, ammonium, organic amino (suchas choline or diethylamine or amino acids such as d-arginine,1-arginine, d-lysine, or 1-lysine), or magnesium salt, or a similarsalt. When compounds of the invention contain relatively basicfunctionalities, acid addition salts can be obtained by contacting theneutral form of such compounds with a sufficient amount of the desiredacid, either neat or in a suitable inert solvent. Examples ofpharmaceutically acceptable acid addition salts include those derivedfrom inorganic acids like hydrochloric, hydrobromic, nitric, carbonic,monohydrogencarbonic, phosphoric, monohydrogenphosphoric,dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, orphosphorous acids and the like, as well as the salts derived fromrelatively nontoxic organic acids like acetic, propionic, isobutyric,maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic,phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric,methanesulfonic, and the like. Also included are salts of amino acidssuch as arginate and the like, and salts of organic acids likeglucuronic or galactunoric acids and the like (see, for example, Bergeet al., “Pharmaceutical Salts”, Journal of Pharmaceutical Science 66:1-19 (1977)). Certain specific compounds of the invention contain bothbasic and acidic functionalities that allow the compounds to beconverted into either base or acid addition salts.

The neutral forms of the compounds are preferably regenerated bycontacting the salt with a base or acid and isolating the parentcompounds in the conventional manner. The parent form of the compounddiffers from the various salt forms in certain physical properties, suchas solubility in polar solvents.

In addition to salt forms, the invention provides compounds which are ina prodrug form. Prodrugs of the compounds described herein readilyundergo chemical changes under physiological conditions to provide thecompounds of the invention. Additionally, prodrugs can be converted tothe compounds of the invention by chemical or biochemical methods in anex vivo environment.

Certain compounds of the invention can exist in unsolvated forms as wellas solvated forms, including hydrated forms. In general, the solvatedforms are equivalent to unsolvated forms and are encompassed within thescope of the invention. Certain compounds of the invention may exist inmultiple crystalline or amorphous forms.

Certain compounds of the invention possess asymmetric carbon atoms(optical centers) or double bonds; the racemates, diastereomers,geometric isomers and individual isomers are encompassed within thescope of the invention. The graphic representations of racemic,ambiscalemic and scalemic or enantiomerically pure compounds used hereinare taken from Maehr, J. Chem. Ed. 1985, 62: 114-120. Solid and brokenwedges are used to denote the absolute configuration of a stereocenterunless otherwise noted. When the compounds described herein containolefinic double bonds or other centers of geometric asymmetry, andunless specified otherwise, it is intended that the compounds includeboth E and Z geometric isomers. Likewise, all tautomeric forms areincluded.

Compounds of the invention can exist in particular geometric orstereoisomeric forms. The invention contemplates all such compounds,including cis- and trans-isomers, (−)- and (+)-enantiomers, (R)- and(S)-enantiomers, diastereomers, (D)-isomers, (L)-isomers, the racemicmixtures thereof, and other mixtures thereof, such as enantiomericallyor diastereomerically enriched mixtures, as falling within the scope ofthe invention. Additional asymmetric carbon atoms can be present in asubstituent such as an alkyl group. All such isomers, as well asmixtures thereof, are intended to be included in this invention.

Optically active (R)- and (S)-isomers and d and l isomers can beprepared using chiral synthons or chiral reagents, or resolved usingconventional techniques. If, for instance, a particular enantiomer of acompound of the invention is desired, it can be prepared by asymmetricsynthesis, or by derivatization with a chiral auxiliary, where theresulting diastereomeric mixture is separated and the auxiliary groupcleaved to provide the pure desired enantiomers. Alternatively, wherethe molecule contains a basic functional group, such as an amino group,or an acidic functional group, such as a carboxyl group, diastereomericsalts can be formed with an appropriate optically active acid or base,followed by resolution of the diastereomers thus formed by fractionalcrystallization or chromatographic means known in the art, andsubsequent recovery of the pure enantiomers. In addition, separation ofenantiomers and diastereomers is frequently accomplished usingchromatography employing chiral, stationary phases, optionally incombination with chemical derivatization (e.g., formation of carbamatesfrom amines).

The compounds of the invention may also contain unnatural proportions ofatomic isotopes at one or more of the atoms that constitute suchcompounds. For example, the compounds may be radiolabeled withradioactive isotopes, such as for example tritium (³H), iodine-125(¹²⁵I) or carbon-14 (¹⁴C). All isotopic variations of the compounds ofthe invention, whether radioactive or not, are intended to beencompassed within the scope of the invention.

The term “pharmaceutically acceptable carrier” or “pharmaceuticallyacceptable vehicle” refers to any formulation or carrier medium thatprovides the appropriate delivery of an effective amount of an activeagent as defined herein, does not interfere with the effectiveness ofthe biological activity of the active agent, and that is sufficientlynon-toxic to the host or patient. Representative carriers include water,oils, both vegetable and mineral, cream bases, lotion bases, ointmentbases and the like. These bases include suspending agents, thickeners,penetration enhancers, and the like. Their formulation is well known tothose in the art of cosmetics and topical pharmaceuticals. Additionalinformation concerning carriers can be found in Remington: The Scienceand Practice of Pharmacy, 21st Ed., Lippincott, Williams & Wilkins(2005) which is incorporated herein by reference.

The term “pharmaceutically acceptable additive” refers to preservatives,antioxidants, fragrances, emulsifiers, dyes and excipients known or usedin the field of drug formulation and that do not unduly interfere withthe effectiveness of the biological activity of the active agent, andthat is sufficiently non-toxic to the host or patient. Additives fortopical formulations are well-known in the art, and may be added to thetopical composition, as long as they are pharmaceutically acceptable andnot deleterious to the epithelial cells or their function. Further, theyshould not cause deterioration in the stability of the composition. Forexample, inert fillers, anti-irritants, tackifiers, excipients,fragrances, opacifiers, antioxidants, gelling agents, stabilizers,surfactant, emollients, coloring agents, preservatives, bufferingagents, other permeation enhancers, and other conventional components oftopical or transdermal delivery formulations as are known in the art.

The terms “effective amount” or a “therapeutically effective amount” ofa drug or pharmacologically active agent refers to a nontoxic butsufficient amount of the drug or agent to provide the desired effect. Inthe oral dosage forms of the present disclosure, an “effective amount”of one active of the combination is the amount of that active that iseffective to provide the desired effect when used in combination withthe other active of the combination. The amount that is “effective” willvary from subject to subject, depending on the age and general conditionof the individual, the particular active agent or agents, and theappropriate “effective” amount in any individual case may be determinedby one of ordinary skill in the art using routine experimentation.

The phrases “active ingredient”, “therapeutic agent”, “active”, or“active agent” mean a chemical entity which can be effective in treatinga targeted disorder, disease or condition.

The phrase “pharmaceutically acceptable” means moieties or compoundsthat are, within the scope of medical judgment, suitable for use inhumans without causing undesirable biological effects such as unduetoxicity, irritation, allergic response, and the like, for example.

Exemplary oral dosageforms include tablets, capsules, films, powders, sachets, granules,solutions, solids, suspensions or as more than one distinct unit (e.g.,granules, tablets, and/or capsules containing different actives)packaged together for co-administration, and other formulations known inthe art. An oral dosage form can be one, two, three, four, five or sixunits. When the oral dosage form has multiple units, all of the unitsare contained within a single package, (e.g. a bottle or other form ofpackaging such as a blister pack). When the oral dosage form is a singleunit, it may or may not be in a single package. In a preferredembodiment, the oral dosage form is one, two or three units. In aparticularly preferred embodiment, the oral dosage form is one unit.

The phrase “unit”, as used herein, refers to the number of discreteobjects to be administered which comprise the dosage form.

Preferred compounds of the invention will have desirable pharmacologicalproperties that include, but are not limited to, oral bioavailability,low toxicity, low serum protein binding and desirable in vitro and invivo half-lives. Penetration of the blood brain barrier for compoundsused to treat CNS disorders is necessary, while low brain levels ofcompounds used to treat peripheral disorders are often preferred.

Assays may be used to predict these desirable pharmacologicalproperties. Assays used to predict bioavailability include transportacross human intestinal cell monolayers, including Caco-2 cellmonolayers. Toxicity to cultured hepatocytes may be used to predictcompound toxicity. Penetration of the blood brain barrier of a compoundin humans may be predicted from the brain levels of laboratory animalsthat receive the compound intravenously.

Serum protein binding may be predicted from albumin binding assays. Suchassays are described in a review by Oravcova, et al. (Journal ofChromatography B (1996) volume 677, pages 1-27).

Compound half-life is inversely proportional to the frequency of dosageof a compound. In vitro half-lives of compounds may be predicted fromassays of microsomal half-life as described by Kuhnz and Gieschen (DrugMetabolism and Disposition, (1998) volume 26, pages 1120-1127).

The amount of the composition required for use in treatment will varynot only with the particular compound selected but also with the routeof administration, the nature of the condition being treated and the ageand condition of the patient and will ultimately be at the discretion ofthe attendant physician or clinician.

VI. a) Testing

Preferred compounds for use in the pharmaceutical formulations describedherein will have certain pharmacological properties. Such propertiesinclude, but are not limited to, low toxicity, low serum protein bindingand desirable in vitro and in vivo half-lives. Assays may be used topredict these desirable pharmacological properties. Assays used topredict bioavailability include transport across human intestinal cellmonolayers, including Caco-2 cell monolayers. Serum protein binding maybe predicted from albumin binding assays. Such assays are described in areview by Oravcova et al. (1996, J. Chromat. B677: 1-27). Compoundhalf-life is inversely proportional to the frequency of dosage of acompound. In vitro half-lives of compounds may be predicted from assaysof microsomal half-life as described by Kuhnz and Gleschen (DrugMetabolism and Disposition, (1998) volume 26, pages 1120-1127).

Toxicity and therapeutic efficacy of such compounds can be determined bystandard pharmaceutical procedures in cell cultures or experimentalanimals, e.g., for determining the LD50 (the dose lethal to 50% of thepopulation) and the ED₅₀ (the dose therapeutically effective in 50% ofthe population). The dose ratio between toxic and therapeutic effects isthe therapeutic index and it can be expressed as the ratio between LD₅₀and ED₅₀. Compounds that exhibit high therapeutic indices are preferred.The data obtained from these cell culture assays and animal studies canbe used in formulating a range of dosage for use in humans. The dosageof such compounds lies preferably within a range of circulatingconcentrations that include the ED₅₀ with little or no toxicity. Thedosage can vary within this range depending upon the unit dosage formemployed and the route of administration utilized. The exactformulation, route of administration and dosage can be chosen by theindividual physician in view of the patient's condition. (See, e.g.Fingl et al., 1975, in “The Pharmacological Basis of Therapeutics”, Ch.1, p. 1).

VI. b) Administration

For any compound used in the method of the invention, thetherapeutically effective dose can be estimated initially from cellculture assays, as disclosed herein. For example, a dose can beformulated in animal models to achieve a circulating concentration rangethat includes the EC₅₀ (effective dose for 50% increase) as determinedin cell culture, i.e., the concentration of the test compound whichachieves a half-maximal inhibition of infected cell growth. Suchinformation can be used to more accurately determine useful doses inhumans.

In general, the compounds prepared by the methods, and from theintermediates, described herein will be administered in atherapeutically or cosmetically effective amount by any of the acceptedmodes of administration for agents that serve similar utilities. It willbe understood, however, that the specific dose level for any particularpatient will depend upon a variety of factors including the activity ofthe specific compound employed, the age, body weight, general health,sex, diet, time of administration, route of administration, and rate ofexcretion, drug combination, the severity of the particular diseaseundergoing therapy and the judgment of the prescribing physician. Thedrug can be administered from once or twice a day, or up to 3 or 4 timesa day.

Dosage amount and interval can be adjusted individually to provideplasma levels of the active moiety that are sufficient to maintaininfected cell growth inhibitory effects. Usual patient dosages forsystemic administration range from 0.1 to 1000 mg/day, preferably, 1-500mg/day, more preferably 10-200 mg/day, even more preferably 100-200mg/day. Stated in terms of patient body surface areas, usual dosagesrange from 50-91 mg/m²/day.

The amount of the compound in a formulation can vary within the fullrange employed by those skilled in the art. Typically, the formulationwill contain, on a weight percent (wt %) basis, from about 0.01-10 wt %of the drug based on the total formulation, with the balance being oneor more suitable pharmaceutical excipients. Preferably, the compound ispresent at a level of about 0.1-3.0 wt %, more preferably, about 1.0 wt%.

Compounds of the inventions may also generally be prepared according tothe sequence outlined in Scheme 1. For example,2-(4-chloro-3-nitrobenzoyl)benzoic acid (1) may be converted to (2) innucleophilic displacement of the chloride with ammonia in an appropriatesolvent. Subsequent conversion of the carboxylic acid intermediate,followed by reaction with hydrazine hydrate in an appropriate solventleads to cyclic compound (5). Reduction of intermediate (5) may becarried out under a range of conditions for example catalytichydrogenation or hydrogen transfer may be employed using palladium oncarbon, platinum oxide or Raney nickel catalysts. Alternatively, ironmetal or tin (II) chloride may also be used as effective reducingagents. Conversion of the resulting phenylenediamine (6) tobenzimidazole (7) can be achieved in one step for example treating (6)with 1,3-bis(methoxycarbonyl)-2-methyl-2-thiopseudourea in acetic acidwith heating. Alternatively, the conversion to (6) may be carried out bytreatment first with methoxycarbonyl isothiocyanate following by heatingin the presence of an appropriate carbodiimide. To introduce othercarbamates, ureas or amides at the benzimidazole 2-position thethiopsueudourea reagent of choice may be straightforwardly prepared.

In an alternative synthetic approach depicted in Scheme 2 compounds ofthe invention may be prepared via electrophilic aromatic substitution ofa suitable precursor such as a optionally substituted cyclic anhydride(8) with a substituted aromatic fragment in a regio-selective manner toafford an intermediate (9).

PARP Enzymatic Activity Inhibition: Determination of IC50 Values forSelected Compounds (Data in FIG. 1)

The half maximal inhibitory concentration (IC50) with respect to PARPinhibition was determined for each test compound by using Trevigen's HTUniversal PARP Assay Kit, according to the manufacturer's protocol(Cat#4677-096-K, Gaithersburg, Md.). This assay measures theincorporation of biotinylated poly(ADP-ribose) onto histone proteins ina 96-well strip well format. This assay is ideal for the determinationof IC50 values of known or suspected PARP inhibitors. Briefly, stocksolutions of each test compound were prepared in DMSO. Histone stripwells were incubated for 30 minutes at room temperature with 50 μl/wellof 1×PARP Buffer to rehydrate the histones. Serial dilutions of eithertest compound were added to appropriate wells. Diluted PARP enzyme (0.5Unit/well) was then added to the wells containing compounds, andincubated for 10 minutes at room temperature. Subsequently, 25 μl of1×PARP Cocktail, containing activated DNA, was distributed into eachwell. Three types of control wells were also analyzed; i. A negativecontrol without PARP was prepared to determine background absorbance.ii. An activity control for PARP Inhibitor Study: 0.5 Unit/well PARP-HSAwithout inhibitors. These wells provided the 100% activity referencepoint. iii. And a PARP Standard Curve: Serial dilution of the PARP-HASstandard were prepared in cold microtubes with 1×PARP Buffer such thatthe total activity is 1 Unit/25 μl, 0.5 Units/25 μl, 0.25 Units/25 μl,0.1 Units/25 μl, 0.05 Units/25 μl, 0.025 Units/25 μl, and 0.01 Units/25μl, 25 μl of each standard was added to triplicate wells. Following a 60minutes incubation at room temperature, the strip wells were washedtwice with 1×PBS+0.1% Triton X-100, and twice with 1×PBS. For activitydetection, 50 μl per well of diluted Strep-HRP was added, and thenincubated at room temperature for 60 minutes. Subsequently, 50 μl perwell of pre-warmed TACS-Sapphire™ colorimetric substrate was addedfollowed by a 15 minutes incubation, in the dark, at room temperature.The reactions were then stopped by adding 50 μl per well of 0.2M HCl or5% Phosphoric Acid and read the absorbance at 450 nm.

The IC50 values were determined by performing non-linear regressionanalysis fitting velocities and the logarithm of inhibitorconcentrations to a sigmoidal dose response with a variable slope modelusing the GraphPad Prism 6.0 software.

ABL Kinase Assays (Data in FIG. 1)

The direct inhibitory effect of the test compounds on the the ABLkinases activity was assessed using the Z′-LYTE biochemical kinaseprofiling assays (SelectScreen Kinase Profiling assays, LifeTechnologies). The Z′-LYTE biochemical assay employs afluorescence-based, coupled-enzyme format and is based on thedifferential sensitivity of phosphorylated and non-phosphorylatedpeptides to proteolytic cleavage. The peptide substrate is labeled withtwo fluorophores (one at each end) that make up a FRET pair. In theprimary reaction, the kinase transfers the gamma-phosphate of ATP to asingle tyrosine, serine or threonine residue in a syntheticFRET-peptide. In the secondary reaction, a site-specific proteaserecognizes and cleaves non-phosphorylated FRET-peptides. Phosphorylationof FRET-peptides suppresses cleavage by the Development Reagent.Cleavage disrupts FRET between the donor and acceptor fluorophores onthe FRET-peptide, whereas uncleaved, phosphorylated FRET-peptidesmaintain FRET. The extent of phosphorylation of the FRET-peptide can becalculated from the Emission Ratio between cleaved and uncleavedFRET-peptides. The Emission Ratio will remain low if the FRET-peptide isphosphorylated (i.e., no kinase inhibition) and will be high if theFRET-peptide is non-phosphorylated (i.e., kinase inhibition).

Using the above described assay, The Test Compounds were screened in 1%DMSO (final) in the well. 10 point titrations, 3-fold serial dilutionswere conducted. Briefly, in a black 384-well plate serial dilutions oftest compound or 100 nL 100× were mixed with kinase bufferpeptide/Kinase Mixture and ATP Solution (10 μM final). After one hourKinase Reaction incubation at room temperature, the development ReagentSolution was added. Subsequently, the fluorescence signals were measuredusing a fluorescence plate reader. Data were analyzed and the IC50 werecalculated with XLfit graphing software using the sigmoidaldose-response model.

The following controls were made for each individual kinase and arelocated on the same plate as the kinase:

0% Phosphorylation Control (100% Inhibition Control)

The maximum Emission Ratio is established by the 0% PhosphorylationControl (100% Inhibition Control), which contains no ATP and thereforeexhibits no kinase activity. This control yields 100% cleaved peptide inthe Development Reaction.

100% Phosphorylation Control

The 100% Phosphorylation Control, which consists of a syntheticallyphosphorylated peptide of the same sequence as the peptide substrate, isdesigned to allow for the calculation of percent phosphorylation. Thiscontrol yields a very low percentage of cleaved peptide in theDevelopment Reaction.

The 0% Phosphorylation and 100% Phosphorylation Controls allow one tocalculate the percent Phosphorylation achieved in a specific reactionwell. Control wells do not include any kinase inhibitors.

0% Inhibition Control

The minimum Emission Ratio in a screen is established by the 0%Inhibition Control, which contains active kinase. This control isdesigned to produce a 10-50% phosphorylated peptide in the KinaseReaction.

Histone H2AX Pharmacodynamic Assay (Trevigen Gaithersburg Cat#4418-096-K) (Data in FIG. 1)

Histone H2AX is a 14 kDa ubiquitous member of the H2A histone familythat becomes rapidly phosphorylated at Serine 139 by ATM and ATR kinasesto yield a form known as gamma-H2AX in response to double-strand DNAdamage and apoptosis. gamma-H2AX is an ideal Pharmacodynamic (PD)surrogate marker to measure molecular responses to a large number ofdrugs; The high throughput ELISA assay measures gamma-H2AX levels incellular extracts and phosphorylation of H2AX in response to therapeuticintervention. This assay documents differences of gamma-H2AX in cellsand tissue.

MDA-MB-436 breast cell lines were treated with either test compound (1μM) Oliparib (1 μM), or DMSO control and lysed according to assayprotocol and L-H2AX levels were measured by gamma-H2AX ELISA assay.Briefly, this assay uses 96-well plates pre-coated with a highlypurified gamma-H2AX antibody. gamma-H2AX from testing sample lysateextracted from cells was captured by the antibody coated on the plate,followed by the addition of anti H2AX mouse IgM which binds to thecaptured targets on the plate. Next a secondary Goat anti mouse IgM HRPwas used to further detect the target complex. Finally, achemiluminescent substrate was added to each well and yielded relativelight units (RLU) that directly correlate with the amount of gamma-H2AXin the testing sample.

Using GraphPad Prism 6.0 software, the changes in the amount ofgamma-H2× in compounds treated cells were calculated as a percentage ofincrease versus its amounts in DMSO treated control cells.

Tubulin Polymerization Assay (Data in FIG. 1)

The high-throughput screening-tubulin polymerization assay kit(Cytoskeleton, Cat. # BK011P) is an economical one step procedure fordetermining the effects of drugs or proteins on tubulin polymerization.Polymerization is followed by fluorescence enhancement due to theincorporation of a fluorescent reporter into microtubules aspolymerization occurs. The standard assay tubulin generates apolymerization curve representing the three phases of microtubuleformation, namely nucleation, growth, and steady state equilibrium.Compounds that interact with tubulin will often alter one or more of thecharacteristic phases of polymerization. For example, the anti-mitoticdrug paclitaxel eliminates the nucleation phase and enhances the Vmax ofthe growth phase. Similarly, the microtubule destabilizing drug,vinblastine (also antimitotic) causes a decrease in Vmax and a reductionin final polymer mass. Thus, one application of this assay is theidentification of novel anti-mitotics.

The direct effects of the test compounds on tubulin polymerization wereinvestigated using the abovementioned Tubulin polymerization assay kit(Cytoskeleton, Cat. # BK011P), as indicated by the manufacturerprotocol. Briefly, bovine brain tubulin (400 μg/sample) in the presenceof either 0.5% DMSO treated (control), 4 μM test compounds, 3 μMpaclitaxel (Cytoskeleton), or 3 μM vinblastine (Cytoskeleton) wasincubated in PEM buffer [80 mm PIPES, 1 mm EGTA, 1 mm MgCl2 (pH 6.8)]containing 1.0 mm GTP (G-PEM) and 15% glycerol, at 37 C. All samples(wells) contained 15% glycerol. The degree of polymerization over timewas measured in a spectrophotometer (Biotek synergy HT plate reader) at350 nm. All time points were plotted and analyzed using GraphPad Prism6.0 software.

The results show the percentage of tubulin polymerization inhibition at60 minutes, as compared to control (DMSO). Of note, at 60 min the steadystate equilibrium was reached for the polymerization curve generatedwith DMSO control treatment. DMSO control was set as 0% inhibition.Positive values depict the percentage of decrease in Vmax and finalpolymer mass, as compared to control. Negative values are inverselycorrelated to degree of nucleation phase elimination and the percentageof increase of the Vmax, as compared to control.

Cell Viability Assay in Solid Multiple Myeloma Cell Lines (Data in FIG.3)

Multiple myeloma (MM) Cells were obtained from the Center for MyelomaTherapeutics at UCSF. MM cells were cultured in RPMI-1640 supplementedwith 20% FBS, penicillin/streptomycin and L-Glutamine. Cells at adensity of 15×103 cells/well (100 ul/well) were dispensed into 96-wellplates One day before treatment with serial dilutions of aforementionedcompounds for 72 h. At the end of treatment, cell proliferation and IC50were determined as mentioned above for solid tumors cell lines.

Tumor Xenografts Studies (Data in FIGS. 4-7)

8 million cells (either OVCAR-8 or MSTO-211H) were mixed with 50%matrigel (BD Biosciences, Bedford, Mass.) and inoculated bySubcutaneously into the flank of 6-8 week old female NOD/SCID (NSG).There were five mice in each of the control groups and five mice in eachof the treatment groups. When tumors reached a volume of 150-250 mm3,the mice were randomized into groups (5 per group) and treated daily byoral gavage with Test compound (at the indicated dosage) or diluent(aqueous 25 mmol/L citrate buffer, pH=2.75) alone as a control. All micewere monitored daily for signs of morbidity and mortality. Mice weightand tumor volume were monitored every 3-4 days for the duration of thestudy.

Single-Dose Pharmacokinetic Study after Oral Gavage Administration (Datain FIG. 8)

To determine the bioavailability of the test compound, we have performeda single-dose concentration curve study, after oral gavageadministration. A single oral dose (10 mg/kg) was administered to 6-8weeks old NSG mice. Subsequently, blood samples were collected from eachmouse, at the various time points (0, 0.5, 1, 3, 8, and 24 hours). Next,plasmas were prepared and drug concentrations in the plasma weredetermined and graphed against time. For each time point, drugconcentrations were evaluated in three different plasma samples.

Evaluation of In Vitro Combination Therapy (Data in FIG. 9)

Cancer cell lines were seeded at 1000 cells per well in 96 well costarplate one day before treatment with serial concentrations of testcompound alone, a chemotherapeutic agent alone (cisplatin or paclitaxel:(Selleck Chemicals)), or 2 drug combination of test compound with eitherchemotherapeutic agents. Vehicle (DMSO) was used as control treatment.Subsequently, the treated cells were incubated at 37° C. for 72 hours.At the end of treatment, cell proliferation was determined by anintracellular adenosine triphosphate monitoring system (Cell-TiterGlo-Promega), and the chemiluminescece signals were read using GoMax 96microplate luminometer.

The inhibitory activity was evaluated by comparing treated versuscontrol data using the GraphPad Prism 6.0 software. The dose inhibiting50% (IC50) of cell viability, for each drug alone or 2 drugs combinationtreatments, was calculated using non-linear regression curve.

For combination drug analysis, the Combination Indices (C.I.) werecalculated based on the equation of Chou-Talalay (Adv Enzyme Regul 1984;22:27-55) for mutually nonexclusive drugs, where a C.I. of <1.3 and >0.9indicates an additive effect: C.I. of >1.3 antagonism; CI of <0.9synergism.CI=[A]_(c)/[A]_(a)+[B]_(c)/[B]_(a)+[A]_(c) X[B]_(c)/[A]_(a)X[B]_(a).  Chou-Talalay equation:

[A]_(c) and [B]_(c) are the concentrations for compound A and compound Bin combination to inhibit x % of cell viability, and [A]_(a) and [B]_(a)are the concentration for compound A and B along to inhibit x % of cellviability.

Nitrosureas        are unique because, unlike most chemotherapy, they can cross the        blood-brain barrier. They can be useful in treating brain        tumors.    -   Metal salts: Carboplatin, Cisplatin, and Oxaliplatin.

Paclitaxel belongs to a class of chemotherapy drugs called plantalkaloids. Plant alkaloids are made from plants. The vinca alkaloids aremade from the periwinkle plant (catharanthus rosea). The taxanes aremade from the bark of the Pacific Yew tree (taxus). The vinca alkaloidsand taxanes are also known as antimicrotubule agents. Thepodophyllotoxins are derived from the May Apple plant. Camptothecananalogs are derived from the Asian “Happy Tree” (Camptotheca acuminata).Podophyllotoxins and camptothecan analogs are also known astopoisomerase inhibitors. The plant alkaloids are cell-cycle specific.This means they attack the cells during various phases of division.

-   -   Vinca alkaloids: Vincristine, Vinblastine and Vinorelbine.    -   Taxanes: Paclitaxel and Docetaxel.    -   Podophyllotoxins: Etoposide and Tenisopide.    -   Camptothecan analogs: Irinotecan and Topotecan.        Antimicrotubule agents (such as Paclitaxel), inhibit the        microtubule structures within the cell. Microtubules are part of        the cell's apparatus for dividing and replicating itself.        Inhibition of these structures ultimately results in cell death.
